Question

An electrical transmission line made of a 2m mm annealed copper wire carries 200 a and has a resistance of 0.4 x 10-4 ohm/cm length. If the surface temperature is 200oc and the ambient temperature is 10oc, determine the heat transfer coefficient between the wire surface and the ambient air and the maximum temperature in the wire. Assume k = 150 w/mk.
